Got a burning question only an archivist could answer? Here’s a great opportunity to ask it: On Ask Archivists Day, a worldwide Twitter event taking place June 9, you can pose an archival question for archivists to address.

Start by following @AskArchivists on Twitter (you'll need a Twitter account, of course). Then on June 9, tweet your question and include the hashtag #AskArchivists. You can direct your question to any archivist who’s joining in, or to a specific participating archive—for example, including @USNatArchives in your tweet directs your question to the US National Archives.
